This
gemstone (or gemstone that is part of this piece of
gemstone jewelry) has been
enhanced
by traditional heat
treatment.
Traditional heat treatment
is used
to
improve a
stones color,
remove color
zoning/banding, and improve clarity. This
treatment is
considered permanent.
The only way to tell if
a colored
stone has
been treated is
for the
stone to be
analyzed by a
lab.
Generally only
gemstone
laboratories
have the
equipment necessary to make
a
qualified judgment with any
certainty.

Untreated
gemstones are rare and should
be
verified by a lab
independent of
the
seller. A good
rule of thumb is
to
always assume a
gemstone
has been
enhanced, unless
valid certification
from a reputable
laboratory is
available. No one that
sells jewelry
or gems should be
doing appraisals,
certifications, or
analysis. It
should
always be an independent
third party
with
no vested
interest in the
sale.?>?>ML:NAMESPACE
